ThunderCats Bullet Point SummaryEdit

Mumm-Ra travels back in time and space to the remains of Thundera in order to find the mighty Sword of Plun-Darr and the Treasure of Thundera.

ThunderCats Bullet Point StoryEdit

Mumm-Ra tells Ma-Mutt about how many years ago, Ratilla, armed with the Sword of Plun-Darr, tried to steal the Treasure of Thundera. However, Jaga was able to foil his plans, banish him for good, and throw the Sword of Plun-Darr into a deep canyon on Thundera. Unfortunately, the sword’s powers could not be contained and it eventually led to the destruction of Thundera. Mumm-Ra and Ma-Mutt then travel through time and space in the Mumm-Raft to the debris of Thundera, in the hopes of locating the Sword of Plun-Darr and the Treasure of Thundera.

The ThunderCats learn of an extraordinary development taking place in deep space. The broken off chunks of Thundera appear to be merging and re-forming the planet. They are shocked to see a New Black Pyramid on “New Thundera”, as well as all the Snarfs in the Valley of the Snarfs being forced by Mumm-Ra and Ma-Mutt to search for the Treasure of Thundera.

While most of the ThunderCats start working on designing and building booster rockets to enable the Feliner to travel to New Thundera, Lion-O and Panthro decide to investigate the Black Pyramid on Third Earth. The two fall into a trap set by Mumm-Ra for them, but manage to escape without suffering any serious injuries. They then return to Cats Lair to work on the booster rockets.

Seeing that the Tower of Omens is only guarded by Lynx-O and the ThunderKittens, Vultureman and Jackalman decide to take advantage of the situation. Vultureman informs the Lunataks and suggests that they attack the tower. Red Eye and Tug-Mug storm the Tower of Omens and incapacitate the three ThunderCats inside.

ThunderCats Bullet Point TriviaEdit

  • The character of Ratilla the Terrible was most likely inspired from the Russian tsar “Ivan the Terrible”
  • This is the first time that we see a very young and clean shaven Jaga.
